Probably not... anybody who is capable of making sense of options like "EagleEngine" or "HQ3X" should be able to just go to the ScummVM folder and launch ScummVM directly. For the rest it would probably just be a source of confusion as there's a lot to be said for ScummVM, but the launcher isn't all it could be.
What I'd still like so see is something like a small ScummVM icon on pages for games that use it, so that people who would benefit from ScummVMs additional options, are actually aware that the game is run through ScummVM.

yeah, i could see how it could get confusing for those who don't know what they're doing, but they should still get credit for all the hard work they put into the open-source engine.

They do on the Thank You page, but I'd argue (in fact I did a couple of times) for some kind of note or icon right on the games page too. For one because I too think it would be fair, but also because it's an important bit of information for people who are familiar with ScummVM and/or DOSBOX and/or other runtimes that GoG may use.

definitely they deserve more credit, hey maybe if they did, these two projects could work together to make a user friendly launcher or something.
thanks for the reply and clarifying it.
